OTTO LEWIN ATTORNEY United States Patent3,284,14? LGQKHNG ARRANGEMENT FOR MULTIPLE DRAWER CABINETS AND THE LIKE@tto Lewiu, York, Pa, assignor to Cole Steel Etguipment (10., Inc, NewYork, NC! a corporation of New York Filed Apr. 23, 1965, Ser. No.45%,3tl0 16 Claims. (Cl. 312-218) This invention relates to cabinets andmore particularly to a locking arrangement for multiple drawer cabinets.

Multiple drawer cabinets, such as those commonly used for filing or aspedestals for desks, are often provided with a mechanism to lock thedrawers thereof against being opened by unauthorized personnel. Suchlocking mechanisms quite often take the form of a bar or slide disposedfor rectilinear sliding movement, along either the sides, back, or topof the cabinet, and in response to the actuation of a key controlledlock, slidably disposed in the cabinet, and interconnected with the baror slide by suitable connecting means.

In conventional cabinet constructions the great majority of the cabinetspace is devoted to the drawers and the suspension mechanism thereforand the area remaining, in which the locking mechanism must be disposed,is considerably small and almost invariably closely disposed to eitherthe sides, top, or the rear walls of the cabinet. Such confined spacinghas a considerable effect on the time required to assemble the lockingmechanism into the cabinet and thus reflects heavily in the costthereof.

it has become common practice, in assembling a locking mechanism intocabinets, to secure some or all of the pieces thereof into the cabinetby the use of intermediate connecting devices, such as, screws, bolts,rivets, etc. and to also interconnect the various elements of thelocking mechanism in the same manner. However, due to the confined areawherein the locking mechanism is to be installed, the alignment of theelements to facilitate the installation thereof in the cabinet and theinterconnection of one with the other by the use of such intermediateconnecting devices is a tedious, cumbersome, time-consuming andexpensive task.

It is therefore an object of this invention to provide an improvedmechanism for securing one or more of a plurality of movable membersagainst movement.

It is a further object to provide an improved locking arrangement for acabinet and the like and especially a multiple drawer cabinet.

A still further object is to provide a locking arrangement for amultiple drawer cabinet wherein the elements of the locking mechanismare interconnected without the use of intermediate connecting devicessuch as screws, bolts, rivets, etc. to facilitate the readyinterconnection thereof and installation within the cabinet.

Another object is to provide a locking arrangement for a multiple drawercabinet wherein safety features are provided to prevent release of thelocking mechanism by unauthorized personnel.

This invention involves multiple drawer cabinets of the type used forfiling, and of the type used as pedestals for desks, wherein a lockingbar is mounted closely adjacent one of the inner walls of the cabinetfor longitudinal rectilinear movement, between a position coacting withstops provided on the drawers to prevent movement of the drawers fromwithin the confines of the cabinet and a position removed from the pathof movement of the drawer stops to permit movement of the drawers fromwithin the confines of the cabinet, such longitudinal rectilinearmovement of the locking bar in turn being effected by linear movement ofa rotary barrel type lock between an unlocked and a locked position, andthrough the intermediary of a member interconnecting the lock andlocking bar and adapted to transmit the linear motion of the lock to thelocking bar; and contemplates mounting the lock and the connectingmember and interconnecting the lock, locking bar and connecting memberwithout the use of intermediate fastening devices, members or elements(such as screws, bolts, rivets, and the like) to thus facilitate rapid,efficient, and economic interconnection thereof.

In carrying out the invention, according to a preferred embodimentthereof, an inner wall of a multiple drawer cabinet has formed from thematerial thereof structure for receiving a lock, for guidinglongitudinal rectilinear movement of the lock, for determining theextent of movement of the lock in one direction, and for coaction withthe bolt of the lock to latch same in a locked position; as well as afulcrum upon which a connector-actuator is pivotally mounted. Theconnector-actuator is formed with a portion facilitating the pivotalmounting thereof on the fulcrum, a hook disposed for coaction with a pincarried by the lock to interconnect the two, and an arm extending intoan open side-d channel formed in the material of a locking bar disposedin the cabinet for movement between raised and lowered positions. Aspring acts on the connectoractuator to urge same in an appropriatedirection to raise the locking bar and move the lock to an unlockedposition.

Other objects, features, and advantages of theinvention in its detailsof construction and arrangement of parts, will be seen from the above,from the following description of the preferred embodiment when considered in conjunction with the drawings, and from the appended claims.

In the drawings:

FIG. 1 is a fragmentary perspective view of a multiple drawer cabinetcut away in part to better show the details of a locking mechanismtherefor embodying the present invention;

FIG. 2 is a fragmentary perspective view cut away in part of theconstruction of the inner forward righthand wall of the cabinet of FIG.1;

FIG. 3 is a fragmentary sectional view taken on line 3-3 of FIG. 1showing the locking mechanism thereof in its actuated and lockedcondition;

FIG. 4 is a view similar to that of FIG. 3 but showing the lockingmechanism thereof in its unactuated and unlocked condition; and

FIG. 5 is a partial fragmentary sectional view taken on line 5-5 of FIG.1.

For convenience, the invention will be described as applied to amultiple drawer cabinet of the type commonly used for the filing ofpapers, documents, and the like, and usually referred to as a filecabinet; it being understood nevertheless that without departing fromthe scope of this invention that subject locking mechanism may beapplied to a drawer cabinet of the type used as a pedestal for a desk ortable or to any other cabinet wherein there are one or more drawersmovable from a position within the confines of the cabinet to a positionexposed from the confines of the cabinet, and which are provided withlocking mechanisms to secure such drawers against movement byunauthorized personnel or for that matter to any construction whereinthere are one or more members which are to be secured against movement.

With reference to FIG. 1 there is shown generally at a file cabinet ofthe kind commonly used for the purpose of storing papers, reports, andthe like, consisting of a casing 12 formed with a top 14, a rear wall16, a right-side wall 18, a left-side wall 20, and front frame 22, andwithin which are slidably disposed drawers 30, each including a frontpanel 32 supporting a drawer handle 34 and supported by a drawer body36.

Suitable suspension mechanism (not shown) is disposed within casing 12to support each drawer 30 for movement between a position wherein frontpanels 32 of drawers 30 are in the same plane as front frame 22 ofcasing 12 to thus prevent access to whatever is stored in drawer body36, and a position wherein front panels 32 are removed from the plane offront frame 22 to permit access to whatever is disposed within drawerbodies 36 of drawers 30.

A locking stop 40 (FIGS. 1 and 4) is fixedly disposed on each drawerbody 36 of each drawer 30 for coaction with a locking ear 46 carried bya locking bar 48 suitably disposed in casing 12 for longitudinal slidingmovement in the directions of arrows A and B (FIG. 1); it beingunderstood that there are lock stops 40 and locking ears 46 for eachdrawer 30 of cabinet 10.

A rib 52 (FIGS. 1, 3 and 4) is formed integral with and extending fromlock bar 48 to form therewith a guide slot or channel 54 and a shelf 56for coaction with an arm 62 of a connector-actuator 64 fulcrumed byforked legs 66 on a fulcrum lug 72 struck from an inner support wall 74(FIGS. 1, 2 and 3) fixedly secured to right side wall 18 and front frame22 of casing 12.

A lock mounting and guide channel 76 (FIGS. 2 and 4) also formed frominner support wall 74 slidably receives the body 80 of a conventionalkey-controlled rotary barrel lock 82 for movement in the direction ofarrows C and D between locked (FIG. 3) and unlocked (FIG. 4) positions.

A shoulder 84 (FIGS. 2 and 3) is formed on guide channel 76 for coactionwith a bolt 86 (FIGS. 1 and 3) of lock 82 which is normally urged to anextended position by conventional means (not shown) and which may bewithdrawn to a retracted position (FIG. 4) by rotation of a barrel 88(FIG. 2) of lock 82 through the use of a suitable key (not shown). Astop 98 (FIG. 2), also struck from inner support wall 74, determines theextent of movement of lock 82 in the direction of arrow C (FIG. 2).

A slot 94, formed in lock 82. is spanned by a pivot pin 96 (FIG. 2)adapted to receive a hook shaped pivot lip 98 (FIG. 3) formed onconnector-actuator 64.

A plurality of lugs 182 (FIG. I) extend out from actuator 64 to spacesame from the inner surface of side wall 18 of casing 12 while an anchorlug 184 (FIGS. 3 and 4) also formed on connector-actuator 64 anchors oneend of an actuator spring 186, the other end of which is anchored toinner support wall 74 as at 168. Spring 1116 urges connector-actuator 64in the clockwise direction (FIG. 4) about fulcrum lug 72 urging, througharm 62 of connector-actuator 64 and shelf 56 of locking bar 48, lockingbar 48 in the direction of arrow A and, through pivot lip 98 ofconnector-actuator 64 and pivot pin 96 of lock 82, lock 82 in thedirection of arrow D.

To assemble lock 82 and connector-actuator 64 within cabinet 10 (lockbar 48 having been disposed therein in substantially conventional mannerduring the assembly of other parts of cabinet 10) the assembler needonly slide lock 82 into lock mounting and guide channel 76;

place forked legs 66 of connector-actuator 64 upon fulcrum lug 72 ofinner wall 74; insert hook shaped pivot lip 98 of connector-actuator 64in slot 94 of lock 82 and about pivot pin 96 thereof; place arm 62 ofconnectoractuator 64 in guide slot 54 of locking bar 48; and anchor oneend of spring 186 to anchor lug 104 of connectoractuator 64 and theother end of spring 186 to anchor lug 108 of inner support wall 74.

It should be noted that due to manufacturing tolerances required in thefabrication of the parts for cabinet 18 that some space will existbetween the periphery of front panel 32 of drawer 30 and front frame 22of casing 12, as more clearly shown in FIG. 5. To prevent insertion of athin element such as the blade 110 of a knife (FIG. 5) by unauthorziedpersonnel there is formed in inner support wall 74 a plurality of spacedribs 112, 114 (FIGS. 2 and 5) such that when knife blade 118 is insertedbetween front panel 32 of drawer 3'0 and front frame 22 of casing 18 itwill be deflected and thus impossible to insert same into a position tolift locking bar 48 from its locked position as shown (FIGS. 1 and 3).

It should be further noted that due to manufacturing tolerances or forother reasons it may be desirable to attach a spring (not shown) tolocking bar 48 to urge same in the direction of arrow B to thusfacilitate movement thereof to its locked position.

When cabinet 10 is in its locked condition the elements of the lockingmechanism are disposed as shown in FIGS. 1 and 3: with lock 82 in itslocked position with bolt 86 thereof latched behind shoulder 84 of lockmounting and guide channel 76 of inner support wall 74;connector-actuator 64 in its actuated condition; and locking bar 48lowered to its locking position with locking ears 46 thereof disposed inthe paths of movement of locking stops 40 of drawers 30, thus preventingmovement of front panels 32 of drawers 38 from their positions in theplane of front frame 22 of casing 12, and access to drawer bodies 36.

To unlock cabinet 18 and permit opening of the drawers 38 thereof oneneed only insert an appropriate key (not shown) in barrel 88 of lock 82and rotate same in the direction to withdraw bolt 86 of lock 82 to itsretracted position (FIG. 4). Spring 186, immediately upon retraction ofbolt 86, acts on connector-actuator 64 to rock same in the clockwisedirection (FIGS. 3 and 4) about fulcrum lug 72 and through the coactionof hook shaped pivot lip 98 of connector-actuator 64 and pivot pin 96 oflock 82 to move lock 82 in the direction of arrow D" (FIG. 2) from itslocked position (FIG. 3) to its unlocked position (FIG. 4). Asconnector-actuator 64 rocks in the clockwise direction arm 62 thereofacts on shelf 56 of rib 52 to move locking bar 48 in the direc tion ofarrow A (FIG. 1) from its lowered or locking position (FIG. 3) to itsraised or unlocking position (FIG. 4) wherein locking ears 46 of lockingbar 48 are removed from the paths of movement of locking stops 40 ofdrawers 30, thus permitting movement of drawers 38 and of front panels32 thereof from the plane of front panel 22 of casing 12.

To lock cabinet 18 one need only apply suitable force against lock 82 tomove same in the direction of arrow C (FIG. 2) until bolt 86 thereof isfree of channel 76 and moved to its extended position (FIGS. 1 and 3) byappropriate mechanism (not shown) behind shoulder 84 of inner supportwall 74. The coaction between pivot pin 96 of lock 82 and pivot lip 88of connector-actuator 64, during movement of lock 82 in the direction ofarrow C, results in a counterclockwise rocking (FIGS. 3 and 4) ofconnector-actuator 64 about fulcrum lugs 72 and against the action ofspring 186. As arm 62 of rocking connector-actuator 64 moves away fromshelf 56. of rib 52 of locking bar 48, locking bar 48 moves in thedirection of arrow B (FIG. 1) under force of gravity until blocking ears46 of locking bar 48 are disposed in the paths of movement of lockingstops 40 of drawers 30 and movement of drawers 30, and of front panels32 of drawers 3t from the plane of front frame 22 of casing 12 isprevented.

Should any drawer 30 be in a position with front panel 32 thereof out ofthe plane of front frame 22 of casing 12, when lock bar 48 is in itslocking at lowered position (FIGS. 1 and 3) its locking stop 40 will notbe located behind its respective locking ear 46 and movement thereof ispossible. Movement of such a drawer 30 to place its front panel 32 inthe plane of front frame 22 of casing 12 results in a coaction betweenits locking stop 40, which is disposed thereon in an inclined manner,and the appropriate locking ear 46 of locking bar 48 and a movement oflocking bar 48 in the direction of arrow A (FIG. 1) until such lockingstop 40 has moved past the path of travel of said locking ear 46 atwhich time, since arm 62 of connector-actuator 64 is still in itsactuated (FIGS. 1 and 3) position, locking bar 48 again moves in thedirection of arrow B (FIG. 1) until it assumes its locked position(FIGS. 1 and 3) with locking ears 46 in the paths of movement of lockingstops 40 of drawers 30.

From the above description it will thus be seen thaat a novel andimproved locking mechanism has been provided for securing one or more ofa plurality of movable members against movement and is adapted for usein cabinets and the like and especially multiple drawer cabinet, whichmechanism is inexpensive and simple in construction, requires a minimumof labor for installation, and does not require the use of intermediateconnecting or attaching elements (such as bolts, screws, rivets, etc.)to enable installation and interconnection of the various elements ofthe locking mechanism.
